' CAR-ROOF.

SPECIFICATION forming part of Letters Patent N 0u 636,781, dated November 14, 1899. Application filed June 3,1899. Serial Na. 719,210. (No model.)

To all whont ?lt may concern.-

Beit known that I, EDWIN (l'EWING, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification.

My invention relates to car-roofs of the kind shown in Letters Patent of the United States, No. 248,905, granted November 1, 1881, to Hiram Aldridge. In the Aldridge patent the car is provided with two roofs or coverings-namely,an outer wooden or board roof and an inner or subroof composed of sheets of corrugated iron arrangedbetween the carlines. In the .Aldridge patent the sheets of corrugated iron extend from the eaves to the ridge-pole and they are adapted to slide across the eaves, their edges being arranged in and guided by grooves in the carlines. Stop-blocks at the eaves are employed' to prevent the plates from slipping after they have been once adjusted to position. The carlines are provided with grooves to prevent water from leaking over the edges of the plates.

In carrying out my invention I provide the car with an outer board or wooden roof and an inner or subroof composed of carlines and corrugated sheets like those in the Aldridge patent; but I provide each carline with an upper fianged plate and with a lower plate, at the edges of which are formed gutters to receive any water that may leak over the edges of the corrugated plates. The edges of the corrugated sheets are arranged in longitudinal grooves in the carlines and are adapted to slide therein. The corrugated sheets are out of contact with the upper flanged plate and with the edges of the gutters in the lower plate, and therefore may be readily slid into and out of place. The plate is formed with upturned inclined portions, from which project troughs or gutters that are arranged below the longitudinal grooves in the carlinebeam; but the bottons of the gutters do not project below the bottom of the beam.

In the accompanying drawings, Figure 1 is a view of a portion of a car-roof embodying my improvements, sone of the parts being broken away the better to illustrate other parts.

Fig. 2 shows a transverse section through one of the end carlines with my improvements applied. Fig. 3 shows a transverse section through one of the internediate carlines embodying my improvements. Figs. 2 and 3 are on a larger scale than Fig. 1.

The outer wooden covering is composed of boards A, which extend from the eaves-beams to the ridge-pole. One of the longitudinal eaves-beams is shown at B, while O indicates the ridge-pole. The carlines D extend from the ridge-poie C to the eaves, their lower or outer ends extending beneath the eavesbeams B and resting upon the eaves-timbers E. The main frame of the car also comprises endbeams F, end planks G, and side planks H, all of which are of the usual well-known construction. The longitudinal boards I rest on the carlines below the board covering A, and the board covering may be secured to these longitudinal boards. The carlines are also supported by longitudinal timbers J, which are arranged about midway between the eaves and the ridge-pole.

My improvements do not relate to the general construction of the frame of the carbody nor to the arrangement of the outer roofing, but are confined to the special construction of the carlines and the manner of connecting the corrugated sheets K thereto. Each intermediate carline is constructed in the manner indicated in Fig. 3, where k indicates the carline-beam, which is preferably made rectangular in cross-section and is provided on opposite sides with longitudinal grooves k', into which project the edges of the corrugated sheets K. To the upper side of each internediate carline is secured a plate L, which at its edges is formed with downturned inclined fianges Z, which project downwardly from the upper longitudinal edges of the carline-beam and over the corrugated sheets. Each internediate carline-beam has secured to its under side a metal plate M, which is bent at m and then formed with gutters m', arranged below the corrugated sheets K. These gutters, it will be observed, are formed from the plates M by bending the plates in line with the longitudinal under edges of the carline-beam, then extending the metal upward in an inclined direction for a short distance, and then bending, it outward to form curved or concaved troughs or gutters, the bottoms of the gutters being` substantially in line with the main body of the plate, which is the bottom of the carline. The arrangement is such that whatever water leaks through the onter wooden roof will flow down the corrugations to the eaves. Very little water will find its way over the edges of the sheets within the grooves k'. XVhatever water does thus fiow over the edges of the sheets will accumulate finally in the troughs or gutters m' and fiow from these gutters down over the eaves. In this way water is prevented from entering the interior of the car. The corrugated sheets K may be slid upward or downward between the carlines. \Vhen adjusted to the proper position, they may he held in place securely by stop-blocks N of usual construction. By removing the stop-blocks and the side plan ks the corrugated sheets may be removed and replaced when desired. The end carline O is similar in all respects to the intermediate carline, (shown in Fig. 3,) except that the groove for the corrugated sheet, the overhanging fiange of the top plate, and the gntter of the bottom plate are onlyemployed on one side of the carline. The sheets K fitting snugly in the grooves 75, there is no danger of rattling, while the flanges Z and the gutters 'm' are not brought into contact with the sheets, but are arranged at suitable distances therefron. Thus the sheets maybe removed and replaeed without changing the relative positions of the platesL and M. Bybending the lower plate M in the manner shown in Fig. 3 two troughs are forned on each side of the carline-that is, a small triangular trough between the inclined portion and the side of the carline and the trough m', which has a curved bottom. \Vater dropping onto the bottom plate will therefore pass down the trough next to the carline. If this trough overfiows, the water passes down the trough m'. By arranging the troughs m' on a level with the bottom of the carline the carlines may be compactly arranged at the eaves, as indicated in Fig. 1.

I claim as my invention- A car-roof comprising a series of sheets of metal, and a series of carlines consisting of beams provided with longitudinal grooves into which the sheets project and in which they are free to slide, upper plates having downturned fianges ont of contact with the sheets of metal, and under plates having upturned, inclined portions at the edges of the beam from which project troughs arranged below the longitudinal grooves of the beams but above the plane of the under sides of the carlines.

In testimony whereof I have herennto subscribed my name.
